THE GRINDING CHARGE OF ROTARY MILLS

2008-7-4  Vinc = the volume of charge, Vcm = grinding media or volume, Minc = weight of the charge, Mcm = weight grinding media, ( Minc ≈Mcm), ρ= the density of the material of grinding media, ρcm = bulk density of grinding media. Bulk density of grinding media can be determined (if ρ and ε are known), with the relation ρcm =ρ(1 −ε) (2)
